Definitions
- the invention concerns the technical field of plastic molding. More particularly, the invention relates to the manufacture of plastic glasses with a stem or base.
- plastic glasses with stems or with bases are made by blow-molding injection.
- this technique because of the large thickness of the rod of the stem, larger than 5 millimeters, this technique has many drawbacks.
- the invention aims at overcoming all or part of the aforementioned drawbacks and in particular at enabling the making of glasses with a stem or with a base in a simple, rapid manner and without any visual defect over the receiving portion of the glass.
- the upper portion of the glass mounted over the stem or the base and shaped so as to contain a liquid is called the «receiving portion».
- the receiving portion may have a flared, trunconical or conical shape, or a flask-like shape, for example.
- an object of the invention is a method for manufacturing a glass with a stem or with a base made of a plastic material, the glass comprising a receiving portion mounted over a base or over a stem, the method being implemented by a rotary tooling comprising a plurality of workstations and at least one mold characterized in that the method comprises the following steps:
- overmolding station b) Overmolding of the stem or of the base over the receiving portion, in order to form a glass with a stem or with a base, the overmolding being carried out on at least one other workstation called overmolding station,
- the cycle time is optimized, in particular by the fact that the receiving portion is made independently of the stem, which allows splitting the method while enabling the making of several parts at the same time. It is possible to make the receiving portion in a color that is different from the stem or the base to the extent that these two elements are made separately. In addition, the vertical mating plane on the receiving portion no longer exists. Furthermore, this method allows for freedom in the design of the stem or of the base. Thus, complex parts, such as a glass provided with a stem having a much larger thickness than a bowl are made on the same press in a simple, rapid and economical manner, while adapting specific injection conditions for each injection of the bowl and of the stem. The material, geometry and surface condition qualities are preserved for the entire container, a pleasant appearance is ensured.
- the step (a) of forming the receiving portion is an injection step on the injection station.
- the step (a) of forming the receiving portion comprises the following substeps:
- blow-molding station blow-molding of the preform injected at substep (a.1) on another workstation called blow-molding station.
- the preform of the receiving portion made at substep (a.1) may comprise a sprue shaped so as to be engaged with the overmolding of the stem or of the base.
- the overmolding step (b) is carried out in one single layer on the overmolding station.
- the overmolding step (b) is carried out in a plurality of layers, at least one layer being made on at least one overmolding station and at least one second layer being made on another workstation called second layer overmolding station.
- second layer overmolding station there may be as many overmolding stations as layers to form the stem or the base of the glass.
- the ejection step (c) is carried out with the mold open or with the mold closed.
- the material used to form the receiving portion and/or the stem is a plastic material such as poly(methyl methacrylate), the Tritan® plastic, the styrene-acrylonitrile copolymer, acrylonitrile butadiene styrene, etc.
- optimal injection conditions are applied for the injection of the receiving portion and the injection of the stem or the base because these are injected with different injection screws and on different stations.
- the manufacturing method according to the invention is carried out on a standard press, which allows keeping a conventional and inexpensive tooling.
- the method comprises an additional step (d) of overmolding an elastomer material or another material over the stem or the base of the glass, said step (d) being carried out on another workstation, different from the injection, ejection and overmolding stations.
- Another object of the invention is a plastic glass fitted with a stem or with a base over which a receiving portion is positioned, said glass being obtained by the manufacturing method according to the invention.
- the glass according to the invention is free of any vertical mating plane at the level of the receiving portion.
- the glass comprises a stem formed by a rod and a base, the stem being positioned over the bottom of the receiving portion of the glass.
- the glass comprises a base positioned below the bottom of the receiving portion of the glass.
- At least one portion of the stem or of the base is coated with an elastomeric material.
- the receiving portion is a flask or a flared cylindrical shape.
